BACKGROUND OF THE INVENTION

A play yard, which is sometimes referred to as a play pen, is acontainment device that typically includes a rigid enclosure having fourside walls, a floor, and an upper opening through which a child may bemoved in and out of the play yard. The rigid enclosure includes upperand lower horizontal frame members that are joined by vertical framemembers, and a solid fabric material is positioned over the framemembers. The side walls typically include a mesh portion that extendsbetween the solid fabric material covering the frame members to allowfor visibility of the child within the play yard and provide adequateair flow to the child. In addition, the frame members may be collapsiblewith respect to each other to allow for easier portability and storageof the play yard.

Many play yards further include a bassinet that can be hung from theupper horizontal frame members of the play yard. In particular, thebassinets, such as the bassinet for attachment in a child's play yarddescribed in U.S. Pat. No. 5,778,465, typically include four side walls,a floor, and a plurality of U-shaped plastic hooks that extend from theupper perimeter of two or more of the four side walls. The plastic hooksare configured for engaging the upper horizontal frame members of theplay yard such that the floor of the bassinet is suspended above thefloor of the play yard. In some products, the bassinet includes a fabricloop along the upper perimeter of two or more of the four side walls,and each fabric loop receives a metal rod. The ends of each metal rodextend outside of the fabric loop and are received into molded U-shapedhooks disposed adjacent the upper horizontal frame members. Some otherproducts, such as the bassinet for suspension in a play yard playdescribed in U.S. Pat. No. 6,434,767, include a combination of theU-shaped plastic hooks and the fabric loop and metal rod engagementmeans to support the bassinet floor above the play yard floor.

In addition, many play yards are collapsed by pulling up on a strap orhandle disposed on the floor of the play yard and attached to thehorizontal frame members and then, by releasing hinges along the upperhorizontal frame members. By pulling up on the strap or handle, thehorizontal frame members and the vertical frame members are drawn towarda central vertical axis extending through the floor of the play yard.However, this strap or handle is inaccessible when the bassinet isinstalled within the play yard, resulting in the additional, oftendifficult step of having to remove the bassinet to access the strap orhandle when the play yard is to be transported or stored.
